VEGFR Tyrosine Kinase Inhibitor III, KRN633 (VEGF-R-TKI III) represents a groundbreaking small molecule inhibitor. VEGFR Tyrosine Kinase Inhibitor III, KRN633 operates by specifically binding to and inhibiting the tyrosine kinase activity of VEGF receptor tyrosine kinase inhibitor III. This kinase, responsible for initiating downstream signaling pathways that modulate angiogenesis, tumor growth, and inflammation, is effectively neutralized upon VEGFR Tyrosine Kinase Inhibitor III, KRN633 binding. Consequently, the activation of downstream signaling pathways is thwarted, effectively suppressing the effects of VEGF receptor tyrosine kinase inhibitor III signaling.
